What about all the electronics?

Amen! I’m really excited to see Rams new twin turbo inline 6 gas engine. I see huge potential for longevity and reliability if done right

I had 43,600 miles on the Ram, and started getting error codes for "service ESC system, Service trailer brake system, and service 4wd system". Was getting these even when no trailer was hooked up and in spite of the fact that the 4wd system worked exactly as it should in all modes. Took it to the dealer and they cleared out the codes, but they returned on my way home. Figured out I could start the vehicle in "auto 4wd" mode and the errors wouldn't appear except for the "service 4wd" code that would intermittently go on and off, but the other two wouldn't show up at all, which was good because when those showed up the cruise wouldn't work. Anyway, to make a long story short, took it back to the dealer, they think it needs a new ABS module, which would take 3 months to source the part. The dealer where I traded it off was also a Ram dealer and they said they would deal with Mopar on it, so I got rid of it.

Sounds interesting Drum! Hope you're doing well buddy.

I am getting a bit of the same deal. My 2020 is in for it's 2nd complete fuel system replacement right now. Over 2 months. I have been raising hell with FCA and the dealer but between the parts backup and all of the other horseshit, I am tired of waiting on stuff. It is a few months too old for a buyback. I was given a 1500 loaner, but that doesn't help move my gooseneck and 5th wheel trailers.

Sounds like it worked out great for you JG.

Friend bought a brand new gmc 1 ton with diesel few months ago. About 2 weeks later in the shop I forget what was wrong but it wasn’t a 1 day fix. They ended having that truck for over a month waiting on parts. My other bud bough a new f350 last year. Paperwork all signed he didn’t even make it off the lot if I remember right. It was a computer chip something I will have ask him when I see him. Sat at ford for a few weeks. They did give him a nice f150 for a loaner truck. GMC didn’t give my buddy chit.

John, it’s a complete ball buster. Mines a new 2020, but since it was over 18 months from time of purchase it doesn’t qualify for lemon law buy back.

Today, I’m seriously getting the Ford 7.3 gasser.

I traded mine as well JG , I was getting 22-23 HWY with the 5.7HemiHybrid. I just needed something for my wife and I barely drove it 6500 miles in one year . I am going to look at another Truck but have not decided on one yet. I have met exactly one person that has a 3.0 duramax and he was ecstatic with it.

Looks like it'll all be electric trucks soon. Putting dual exhaust on my 5.0 f150 hopefully this weekend

Talked to my nephew in Oregon logging country and some loggers are using the 3.0 GM diesel in their crummies will be interesting how they hold up.

Now over 60k in the 3.0 Duramax. I did have a check engine light that turned out to be the need to replace one of the sensors in the exhaust system. Other than that which was under warranty, no issues

Good stuff. Thanks for the update!

Duckster, thats better than a toyota Tacoma I bought few years back:

Long before 60k miles:
Front differential disconnect inop lost 4wd
Rear axle seal

Great engine in that truck. I'm building a gm inline 6 right now: 292 chevy.

Forged .060 high compression pistons, roller cam, roller rockers, clifford headers, clifford intake manifold. Davis Unified Ignition (HEI)

That 292 sounds like it'll be a good motor Mainer. What are you putting it in?

Beretz, developed a bad oil leak in my 2002 7.3 powerstroke. So just putting together a simple/cheap gas truck till I get that 7.3 pulled and overhauled.

292 is going in a 1968 k20 along with 4:56 geared axles and hydroboost brakes from a military m1028 suarebody with 13000 miles. Axles have detroit locker in rear, limited slip diff in front. 1 and 1/4 ton leaf springs.

That old K20 should be a beast! Maybe not friendly on gas but man, if you can keep it fed you should be able to get about anywhere you’ve got business taking a truck.

I just bought one last Oct new, now have about 10,700 mile. Love it so far and after much research, it’s what I was looking for.
Around town average driving get about 23 mpg, on trips including running around when i get there usually 26 mpg average. That’s numbers from the computer.
It also shows best mileage over 50 miles. 31.2. I have averaged 29 for interstate trips.

Very happy

My average for 75% highway and 25% city has been pretty steady at 24.5 mpg. That is with larger than factory AT tires

Have a 2022 Trail Boss with 15k miles and have averaged 21 since new. Not what I was expecting and definitely not worth the extra cost of diesel and DEF.
